Predicting cumulative deaths in state

  • WI correpondence between Cumulative cases and deaths (at time lag)
  • Starting with late May, after daily tests regularly above 6000
[1] "The number of  cumulative deaths, at a lag of 21 days, are approximately 1.4 times number of cumulative cases to the 0.64 power."
[1] "We thus predict that on 2022-02-09 the cumulative number of deaths in WI will be 12803"
